Hayao Miyazaki's first CG film for the Ghibli Museum. This is the 10th film made for the museum. Just before dawn, Boro the Caterpillar hatched from an egg among patches of scrub grass. Looking around for the first time in fascination, he noticed the brilliance of the morning sun and a deliciousness in the air. As the sun lights up the grove, the borogiku (groundsel) leaves began to photosynthesize. "The air and water taste great!" Boro stepped out into the world of caterpillars' friends and foes. Computer graphics and hand-drawn animation were combined to create a world seen through the eyes of an insect, and all sound effects were provided by the voice of Tamori.
